Abstract
The present disclosure is directed to a crystal of L-glufosinate and a preparation method and use thereof. The crystal of L-glufosinate includes five crystal forms, namely crystal form A, crystal form B, crystal form C, crystal form D and crystal form E. These crystal forms show excellent effects in stability, hygroscopicity, storage, etc., which are beneficial to the preparation, separation and storage of herbicides, and at the same time have good solubility and good pharmacokinetics, which is further beneficial to improve the level and speed of herbicides to control weeds.
